Abstract

Advances in information technology and improvements in internet network infrastructure, it is becoming easier for everyone to get and work using information technology. Influencers appear when the methods used in marketing use influencer marketing techniques. Currently, many target marketers use child influencers to target children. Because children are considered unable to determine their own will, the role of various parties is needed to prevent child influencers from being exploited. Using or directing children as influencers compromises children's emotional and physical development. This article uses a normative juridical approach, analyzed qualitatively. According to literature research, Indonesia ratified the UN Convention on the Rights of the Child, as shown by Presidential Decree Number 36 of 1990 concerning Ratification of the Convention on the Rights of the Child, Amendments to the 1945 Constitution, including Article 28B Paragraph (2), and Law -Law Number 23 of 2002 concerning Child Protection. During the implementation of child protection instruments, all relevant parties must prioritize initiatives that protect children from exploitation.

Abstract

This study aims to analyze the growth of Rhizophora apiculata in the silvofishery system in Simpang Tiga Jaya Village, Tulung Selapan District, Ogan Komering Ilir Regency, South Sumatra Province. The research was conducted to compare the effects of two planting locations—pond and riparian areas—and two types of seed sources, namely propagules and natural wildings, on the growth and survival rate of Rhizophora apiculata. A quantitative experimental method was used, with observations conducted over 4 month on variables such as plant height, stem diameter, number of leaves, root length, and root weight. The results showed that seedlings originating from propagules exhibited higher growth rates and survival percentages compared to wilding seedlings. The highest survival rate was observed in treatment M2S2 (riparian location + propagules) at 76.67%, followed by M1S2 (pond location + propagules) at 72.22%. Soil analysis revealed that the pond location had higher nutrient content, thus supporting more optimal plant growth. Overall, the source of seedlings was identified as the main factor contributing to the successful rehabilitation of Rhizophora apiculata within the silvofishery system.

Abstract

Matrix is ​​a branch of Linear Algebra, which is one of the important topics in mathematics. In line with the development of science, the application of matrices is often found in everyday life, both in the field of mathematics itself and for other disciplines. This use is widely used in solving problems related to everyday life, for example in banking applications, in the world of sports, and in the economic field. Whereas in mathematics, matrices can be used to handle linear models, such as finding solutions to systems of linear equations. On the other hand, there are also many problems that often arise related to the problem of the matrix itself, including how to determine the inverse of a matrix, which is also known as the inverse of a matrix. While the problem that often arises in finding the inverse matrix is ​​if the matrix is ​​neither square nor singular. In fact, a matrix is ​​said to have an inverse if and only if it is a square matrix and is non-singular. An interesting discussion in matrix theory is determining the inverse of a matrix. Inverses have an important role in solving several problems in matrices and are widely used in mathematics and applied sciences. Many methods are used in finding the inverse matrix including substitution, matrix partitioning, adjoining matrix, Gaussian elimination, Gauss-Jordan elimination, elementary row operations (OBE), elementary inverse matrix multiplication, and LU matrix decomposition. This article explains how to solve an inverse matrix of order 3x3 using elementary row operations (obe) method.

Abstract

Terumbu karang merupakan salah satu ekosistem laut yang paling rentan terhadap pencemaran laut yang disebabkan oleh aktivitas antropogenik dan perubahan iklim. Studi ini bertujuan untuk mengkaji dampak pencemaran laut terhadap distribusi dan adaptasi terumbu karang di berbagai zona biogeografi serta memberikan rekomendasi konservasi yang efektif. Kajian literatur menunjukkan bahwa pencemaran laut, termasuk limpasan limbah domestik dan industri, peningkatan kadar nutrien yang menyebabkan eutrofikasi, serta akumulasi polutan kimia dan mikroplastik, telah menyebabkan degradasi terumbu karang secara signifikan di berbagai wilayah. Dampak pencemaran ini bervariasi antar zona biogeografi, tergantung pada faktor oseanografi dan tingkat tekanan lingkungan. Beberapa spesies karang menunjukkan mekanisme adaptasi melalui perubahan simbiosis dengan zooxanthellae yang lebih tahan terhadap kondisi ekstrem serta peningkatan toleransi terhadap sedimentasi dan polutan kimiawi. Namun, adaptasi ini memiliki keterbatasan dan tidak dapat sepenuhnya melindungi ekosistem terumbu karang dari tekanan lingkungan yang semakin meningkat. Oleh karena itu, upaya konservasi yang komprehensif diperlukan, termasuk pengurangan sumber pencemaran, pemantauan ekosistem, restorasi terumbu karang, serta peningkatan kesadaran masyarakat dan pengembangan zona perlindungan laut. Dengan langkah-langkah ini, diharapkan ekosistem terumbu karang dapat tetap lestari dan memberikan manfaat ekologis serta ekonomi bagi keberlanjutan lingkungan laut.
